Ethereum Co-Founder Joseph Lubin Highlights the Risks of AI Domination by Big Tech

According to Joseph Lubin, the next significant turning point for crypto will be driven by artificial intelligence. Lubin, who is set to speak at Consensus Miami 2026, believes that autonomous agents can facilitate transactions, coordination, and verification on decentralized networks, utilizing cryptocurrency infrastructure as the foundation for machine-driven activities. He expressed his support for the idea that blockchain technology is suited for machine intelligences but does not envision humans being replaced. Instead, increasingly sophisticated interfaces will simplify complexity, enabling users to interact with crypto systems through intent rather than manual inputs, with AI acting as an intermediary layer between people and protocols. However, Lubin cautioned that if AI infrastructure remains concentrated among a few large tech firms, it could lead to trouble. He emphasized the importance of decentralized systems and cryptography in ensuring accountability and enabling machines to verify each other in transparent environments. As part of this broader shift, products like MetaMask are evolving to reflect the change. Lubin described the wallet as a new type of neobank that users own and control, marking a transition toward a personal money operating system. AI-powered agents could manage assets, execute transactions, and navigate the growing decentralized economy on behalf of users. Lubin also pointed to structural changes in the Ethereum ecosystem, including the rise of corporate chains. He expects companies to seek higher throughput and greater control over their infrastructure, leading to the increased adoption of corporate chains. However, he emphasized that assets are best issued on Ethereum's base layer to ensure durability. Stablecoins, a rapidly growing sector in crypto, are part of this transition but not the ultimate goal. Lubin described them as a stepping stone toward more fully decentralized financial systems, noting that current models rely heavily on centralized issuers. Over time, he expects the growth of decentralized collateral to enable more robust, crypto-native forms of money. Regarding tokenization, Lubin suggested that traditional finance and decentralized finance are converging, combining centuries of financial innovation with newer blockchain-based systems. This convergence will result in a more granular and programmable global economy. Lubin adopted a measured tone when discussing long-term technical risks like quantum computing, stating that Ethereum developers have been preparing for years and view it as a natural part of the platform's evolution.
